10 years agoe1000e: allow tx of pre-formatted vlan tagged packets
Arthur Jones [Thu, 19 Mar 2009 01:13:08 +0000]
e1000e: allow tx of pre-formatted vlan tagged packets

As with igb, when the e1000e driver is fed 802.1q
packets with hardware checksum on, it chokes with an
error of the form:

checksum_partial proto=81!

As the logic there was not smart enough to look into
the vlan header to pick out the encapsulated protocol.

There are times when we'd like to send these packets
out without having to configure a vlan on the interface.
Here we check for the vlan tag and allow the packet to
go out wiht the correct hardware checksum.

Thanks to Kand Ly <kand@riverbed.com> for discovering the
issue and the coming up with a solution.  This patch is
based upon his work.

10 years agomac80211: deauth before flushing STA information
Herton Ronaldo Krzesinski [Tue, 10 Mar 2009 13:11:09 +0000]
mac80211: deauth before flushing STA information

Even after commit "mac80211: deauth when interface is marked down"
(e327b847 on Linus tree), userspace still isn't notified when interface
goes down. There isn't a problem with this commit, but because of other
code changes it doesn't work on kernels >= 2.6.28 (works if same/similar
change applied on 2.6.27 for example).

The issue is as follows: after commit "mac80211: restructure disassoc/deauth
flows" in 2.6.28, the call to ieee80211_sta_deauthenticate added by
commit e327b847 will not work: because we do sta_info_flush(local, sdata)
inside ieee80211_stop (iface.c), all stations in interface are cleared, so
when calling ieee80211_sta_deauthenticate->ieee80211_set_disassoc (mlme.c),
inside ieee80211_set_disassoc we have this in the beginning:

         sta = sta_info_get(local, ifsta->bssid);
         if (!sta) {

The !sta check triggers, thus the function returns early and
ieee80211_sta_send_apinfo(sdata, ifsta) later isn't called, so
wpa_supplicant/userspace isn't notified with SIOCGIWAP.

This commit moves deauthentication to before flushing STA info
(sta_info_flush), thus the above can't happen and userspace is really
notified when interface goes down.

Helmut Schaa [Mon, 9 Mar 2009 14:47:08 +0000]
mac80211: handle failed scan requests in STA mode

If cfg80211 requests a scan it awaits either a return code != 0 from
the scan function or the cfg80211_scan_done to be called. In case of
a STA mac80211's scan function ever returns 0 and queues the scan request.
If ieee80211_sta_work is executed and ieee80211_start_scan fails for
some reason cfg80211_scan_done will never be called but cfg80211 still
thinks the scan was triggered successfully and will refuse any future
scan requests due to drv->scan_req not being cleaned up.

If a scan is triggered from within the MLME a similar problem appears. If
ieee80211_start_scan returns an error, local->scan_req will not be reset
and mac80211 will refuse any future scan requests.

Hence, in both cases call ieee80211_scan_failed (which notifies cfg80211
and resets local->scan_req) if ieee80211_start_scan returns an error.

mac80211: Fix WMM ACM parsing and AC downgrade operation

Incorrect local->wmm_acm bits were set for AC_BK and AC_BE. Fix this
and add some comments to make it easier to understand the AC-to-UP(pair)
mapping. Set the wmm_acm bits (and show WMM debug) even if the driver
does not implement conf_tx() handler.

In addition, fix the ACM-based AC downgrade code to not use the
highest priority in error cases. We need to break the loop to get the
correct AC_BK value (3) instead of returning 0 (which would indicate
AC_VO). The comment here was not really very useful either, so let's
provide somewhat more helpful description of the situation.

Since it is very unlikely that the ACM flag would be set for AC_BK and
AC_BE, these bugs are not likely to be seen in real life networks.
Anyway, better do these things correctly should someone really use
silly AP configuration (and to pass some functionality tests, too).

Remove the TODO comment about handling ACM. Downgrading AC is
perfectly valid mechanism for ACM. Eventually, we may add support for
WMM-AC and send a request for a TS, but anyway, that functionality
won't be here at the location of this TODO comment.

GRO: Move netpoll checks to correct location

As my netpoll fix for net doesn't really work for net-next, we
need this update to move the checks into the right place.  As it
stands we may pass freed skbs to netpoll_receive_skb.

This patch also introduces a netpoll_rx_on function to avoid GRO
completely if we're invoked through netpoll.  This might seem
paranoid but as netpoll may have an external receive hook it's
better to be safe than sorry.  I don't think we need this for
2.6.29 though since there's nothing immediately broken by it.

This patch also moves the GRO_* return values to netdevice.h since
VLAN needs them too (I tried to avoid this originally but alas
this seems to be the easiest way out).  This fixes a bug in VLAN
where it continued to use the old return value 2 instead of the
correct GRO_DROP.
